TOY.

Specification of Letters Patent.

Patented July 1, 1919.

Application filed February 25, 1918. Serial No. 218,999.

T 0 all whom it may concern:

Be it known that I HERMAN E. LUND- earn, a citizen of the United States, residing .at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Toys, of which the followingis a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part "of this specification.

My invention relates to toys and more particularly to a mechanically operated toy which is both amusing and instructive. The toy simulates in miniature the construction and operation of a connected wind-mill, engine, and pump.

An important feature of thetoy is that the wind-mill in its entirety may be dismounted and collapsed and'packed away I in a small box when it isdesired to ship. or store the same.

Thevarious parts are of simple construction and are easy to assemble and inexpensive to manufacture.

I do not intend to be limited tothe form illustrated and hereinafter specifically described, as itis obvious that the 'principle and operation may appear in various forms within the scope of my invention.

In order to inform those skilled in the art how to put my invention into practice, I shall now describe in detail one preferred embodiment of my invention.

In the accompanying drawing, Figurel. is

an isometric view of my improved toy.

Fig. 2 is a longitudinal cross-section of the boiler taken on line 2-2 of Fig. 1.

Fig. 3 is a cross-sectional view taken on line 3--3 of Fig.2, and

Fig. 4 is a detailed view of the fan shaft.

Referring moreparticularly to the draw ings, my invention comprises a main base 1, having mounted thereon a wind-mill 7, an engine 8 and a boiler 9. The tower com prises a pair of U-shaped members and 4 with their ends bent laterally so as to form the hooks 5 and 6. These U-shaped mem bers are preferably of such material and form as to have a slight resiliency to enable them tojbe squeezed together at their lower ends to disengagethe hooks 5 and 6 from the aperture lugs 2. It will-therefore be noted that the tower can be dismounted from the base without theflse of nuts, bolts or the U-shaped member 3 is a spacing bar 10. One end of the spacing bar 10 ispivoted on one leg of the member 3 as shown at 11 while the otherend forks the adjoining leg of the member 3. In like manner a bracing bar 12 spans the legs of the U-shaped member 4. If greater rigidity of the tower 7 is deemednecessary, I contemplate using crossbraces 13, which are pivoted to the U-shaped members Sand 4.

Passing through the upper cross-bars 14 and 15 isa fan shaft 16 which has a fan 32 mounted on one of its ends. Atthe opposite end, the shaft 16 carries a pulley 17 which is held in place by means of the collar 18 and the set'screw 19 as shown in Fig. 4. Directly in the center of the floor of the tower 7 is a well 38, surroundedby a platform 19. The. well or pump shaft 2 0 extends up through this well38 and is fastened to the crank portion 16 ofthe shaft'16...

The boiler 9 is mounted upon a base 24, which in turn is fastened to the main base 1. Longitudinally mounted within the boiler 9 is a shaft 25. Referring to Fig. 2 it will be noted that a torsion spring34 encirelse this. shaft 25 and has one was ends fastened to a crown gear 26 that is freely mounted upon one end of the shaft 25. This crown gear 26 meshes with the spur gear 27, which ismounted upon an engine shaft 28 thatextends transversely through the boiler 9. To add to the miniature likenessof the toy, I placed ajfly wheel 29 at one end of the engine shaft. The other end ofthe engine shaft is connected through an eccentric pin 41 to the connecting rod 30of the engine 8.

Thebelt 36 affords the driving means-be tweenthe pulley 31 and the engine shaft, the idler P l y 23 e th pu l y 1 not he Wind- 1 A ratchet wheel 33 is secured to the shaft 25 adjacent the opposite end of the boiler 9, The handle 37 is made concentric with the shaft 25. The teeth of the ratchet wheel 33 are adapted to engage a pair of pawls 40 which have reciprocating motion in the slot 35 of the bracket 36. The bracket 36 is mounted upon a block 39, secured to the base 24. The pawls 40 are in the form of small tongues bent laterally from the oscillating plate 42.

Referring to Fig. 2 itwill be seen that the plate 42 is uided by. means of the lip 43, embracing the top of the plate 36,:

and also by a lip 44 struck up from the bracket 36 and embracing the lower edge of the plate 42. V

Preferably the ratchet wheel 33 is provided with an odd number of teeth and the inner ends of the pawls 10 are spaced apart less than the diameter of the ratchet wheel measured over the tips of the ratchet teeth. In this way the ratchet wheel is adapted to reciprocate the plates 42 with the two pawls 40, the ratchet tooth in engagement with one pawl drawing the opposite pawl toward the shaft and causing it to engage the next tooth in succession so as to prevent a retrograde movement of the shaft.

The operation of my improved toy is as follows: 7

By revolving the handle 37 in the direction of the arrow, and holding the fly wheel 29, the torsion spring 34L may be given sufiicient energy to run the toy a considerable time. Upon releasing the fly wheel 29 the crown gear 26 will drive the engine shaft 28 through the spur gear 27.

V The engine shaft 28 imparts oscillating movement to the piston rod 30, and the belt 36 then drives the fan shaft 16, and rotation of the fan resulting in operation of the pump. The handle 37 may be rotated continuously, the spring then serving as a yield ing driving connection. 7

It will be seen that I have invented an instructive and amusing toy. I do not intend to be limited to the details shown except as they are defined in the appended claims.

What I claim is:

1. In a toy, a pump having a reciprocating plunger, a tower surrounding said plunger, a driving shaft at the top of the tower operatively connected to the plunger, an engine, a belt-operatively connecting the engine withsaid shaft, and means for driving said engine. 7

2. In a toy, a pump having a reciprocating plunger, a collapsible tower surrounding said plunger, a driving shaft at the top of the tower operatively connected to said plunger, an engine, a belt operatively connecting the engine to said shaft, a boiler, a

power shaft extending through the boiler, adapted to be rotated by hand, and gearing operatively connecting said power shaft with said engine for driving same.

3. In a toy, an engine, a wind-mill comprising a fan, a fan shaft, a well, a pump shaft having its lower end mounted within said well and its upper end engaging with said fan shaft, a pulley mounted at one end of said fan shaft, an idler pulley, and a pulley mounted upon the engine shaft, a belt connecting said pulleys, and means for rotating said engine shaft.

4. In combination, a wind-mill, an. engine, a boiler, an engine shaft extending through said boiler, said engine shaft and said wind-mill being operatively connected to each other, a spring within said boiler, a manually operated means for energizing said spring, means for transmitting sald energy to said engine shaft, and ratchet means for holding said spring energized.

5. In a toy, a combination of a wind-mill, a well, an engine, and a boiler, said windmill comprising a shaft having a pulley mounted at one end and a fan at the other end, a pump shaft engaging said fan shaft and extending into said well, an engine shaft projecting laterally through said boiler,'having one end connected to the piston rod of said engine and a fly wheel mounted at the other end thereof, a motor within said boiler, comprising a spring, a crown gear connected thereto, a spur gear mounted on said engine shaft and engaging said crown gear, and belt means connecting said fan'shaft pulley and said engine shaft.

6. In a toy, a combination of a wind-mill having demountable tower, a fan shaft, mounted within said tower, a fan and pulley mounted upon said fan shaft, means for removing said fan and pulley from said fan shaft, an engine, and a spring motor for operating said fan shaft.

In witness whereof, I hereunto subscribe my name this 19 day of February, A. D. 1918.
